I use manually generating hierarchy mode as it is described in http://www.telerik.com/help/winforms/gridview-hierarchical-grid-object-relational-hierarchy-mode.html
For bool fields I use GridViewCheckBoxColumn.
When I change bounded bool field in child object, the changes in CheckBoxEditor are not displayed (and vice versa, when I click a CheckBoxEditor, the changes are not reflected in object).
If I press a header for reorder, then the changes are partially displayed, but couple of checkbox are not change.

In debugger I see (rgvMain is RadGridView):

rgvMain.CurrentRow.ChildRows[1]:

    {Telerik.WinControls.UI.GridViewHierarchyRowInfo}

UPD:

It helps:

 foreach (var template in rgvMain.CurrentRow.ViewTemplate.Templates)
                    {
                        template.Refresh();
                        template.Refresh(); // First time not work
                    }

Hello Viktor,

Thank you for contacting Telerik Support.

When you use RadGridView bound to custom objects, it is necessary to notify the RadGridView for any further changes related to the DataBoundItems. It is necessary to refresh the corresponding template, to which the current row is belonging to, together with refreshing the MasterTemplate:
private void radButton1_Click(object sender, EventArgs e)
{
  Product  row = this.radGridView1.CurrentRow.DataBoundItem as Product;
  if (row!=null)
  {
      row.Discontinued = !row.Discontinued;
      this.radGridView1.CurrentRow.ViewTemplate.Refresh();
      this.radGridView1.MasterTemplate.Refresh();
  }
}

You can refer to our Binding to Hierarchical Data Programmatically help article, where the the changes are automatically refreshed. Our Reflecting Custom Object Changes in RGV help article is quite useful as well about reflecting changes to RadGridView.

I hope this information helps. Should you have further questions, I would be glad to help.
